But when? The US started all of it's own wars until WW2.Probably about the same, after the Constitution is amended to allow a standing army once the need becomes obvious (eg, as soon as a serious war or war threat happens).
The US was expanding against dozens of Indian tribes. As soon as one (say, the Seminoles) puts up too much of a fight for local militias, or there's some sort of secession/nullification crisis, or there's a territorial dispute with Mexico or the British, or... Hell, the big reason the Articles of Confederation were replaced with the Constitution was the need for a stronger central authority; the people writing and voting on said Constitution knew that said stronger central authority needed some sort of military to be able to do its job of protecting the country.But when?

Sailing up the Mississippi?Perhaps Western expansion of the fledgling United States might have stopped at the Mississippi River for quite some time? British sea power or in this case river power.
IIRC that's what they actually did, they had a few states pool together forces that were raised for a year's time into the First American Regiment. This regiment and a bunch of state militias were then annihilated at the Wabash by Little Turtle and Blue Jacket and Congress finally realized Washington was right and America needed some form of standing professional army.How about if, instead of simply NOT having a standing army, this ATL US relied on some system of regular state forces (allocated through some means to be determined) that are maintained in an active status by the states but made available to the federal government?
